This adapter is made to allow the installation of a K-Series engine with the 02-04 K20 engine harness. It will also work for our all RYWIRE K-Series engine harnesses. K1 & K2 types!

This wire harness connects your K-Series engine harness to your chassis interior harness while adding the E-plug and all its functions. This harness is primarily made for a K-Pro or Re-Flashed ECU but can be used with a stock RSX ECU provided you have bypassed the immobilizers accordingly.

The following Chassis Adapters are custom made:
priced accordingly at $349.

90-91 Integra [+$100]

92-93 Integra [+$100]

90-93 Accord [+$100]

94-97 Accord [+$100]

98-01 Accord [+$100]

You won't use your factory Engine harness with the K20, but you still continue to use your Interior harness with this conversion, so don't toss it!
